FAUCET-LOCK.

Specification of Letters Patent.

Patented Feb. 6, 1906.

as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to certain improvements in looks for faucets,stop-cocks, and th An object of the invention is to produce a simple andvery effective faucet-lock which can be manufactured economically andcan be easily and quickly applied to and lifted from the faucet andwhich, if so desired, will retain its locking position on the faucet bygravity.

The invention consists in certain novel features in construction and inarrangements or combinations of parts, as more fully and particularlypointed out hereinafter.

Referring to the accompanying drawings, which show as examples forpurposes of explanation constructions from among others within thespirit and scope of my invention, Figure 1 is a perspective view of afaucet having a T turn-key or handle, showing a form of my lock appliedthereto, dotted lines showing the complete formation of the parts. Fig.2 is a detached perspective view of the lock reversed. Fig. 3 is aperspective view of a faucet having its turn-plug provided with a singlecrank-handle or turn-key, showing a somewhat different form of my lockapplied thereto and fastened by a chain and padlock.

The faucet 2(shown in Fig. 1) has its valve or turn-plug'3 provided witha cross or T turn-key or handle 4, by which the faucet is opened andclosed. When the faucet is closed, this handle is arranged transverselyof the longitudinal axis or length of the faucet, as shown in Fig. 1.

The valve or turn-plug 3 of the faucet shown in Fig. 3 is" provided witha single crank-handle or turn-key 5-that is, the handle extends in onedirection only from the upper end of the valve. When thevalve is inposition closing the faucet, this handle 5 is arranged transversely ofor at right angles to the longitudinal axis of the faucet.

My improved lock is designed to fit on the faucet when the same isclosed and straddle the turn-key or handle and prevent movement thereofto open the faucet for the discharge of liquid.

The lock consists of a single usually elongated block 6, preferably castor otherwise formed in one piece of metal. The top or up per end of thisblock is preferably closed and its side and end walls or faces areusually flat. The lower end of the block is bifurcated or slotted at 7to straddle the pipe or casing of the faucet and fit down. on and extendbelow the same along diametrically opposite sides of the valve or plugcasing of the faucet. The slot 7 extends upwardly through andlongitudinally of the end walls or faces of the block. When the block isformed to lock a T turn-key, as shown in Fig. 1, the block is bifurcatedat right angles to the plane of the bifurcation 7 by longitudinalvertical slots 8 open at their lower ends and extending through the sidefaces of the block. The slots 8 through the side walls of the block arein the same vertical plane and extend through the lower end of the blockand longitudinally thereof almost to the top end of the block and are ofsuch dimensions as to receive and straddle both ends of the turn-key 4and prevent operative movement of said turn-key. The block is hollow andopen at its lower end and is so slotted or bifurcated upwardly from itslower end about as described that when the valve is in position closingthe faucet the block can be slipped down over the faucet with theturn-key ends entering and projecting through the slots 8 and thebifurcation 7 receiving the longitudinal body or casing of the faucet.The block fits down on and rests against the body or casing of thefaucet and is held against horizontal movement thereon by the dependingends or legs formed by the bifurcation 7. The side walls and slots 8 ofthe block are so formed that it is impossible to operatively turn ormove the turn-key while the block is in place on the faucet, renderingit necessary to lift the block from the faucet before the valve can beturned to open the faucet. The block will maintain. its position on thefaucet by gravity and can be easily slipped on and from the faucet, asthe block slides vertically and freely thereon.

If so desired, means can be provided to loosely attach the block to thefaucet or to the wall adjacent to the faucet to prevent loss orlIllSPliLOGlllGlll? of the block. For instance, in Fig. 3 I show theblock provided at its upper end with a ring or eye 9, to which anattaching chain or connection can be fastened. Also, if so desired, aloose chain or connection 10 can be fastened at one end to said eye 9,so that the chain can be passed down under the faucet-handle when theblock is applied thereto with the free end of the chain extendedupwardly and connected to the eye 9 by a padlock 11 or other suitablemeans to hold the chain under tension if de sired, and thereby drawingthe block down onto the faucet and positively locking the block on thefaucet. WVhere this arrangement is employed, the padlock must beunlocked and released from the free end of the chain 10 before the blockis free to be lifted from the faucet. A very simple and yet exceedinglyeffective positive locking device is thus provided, whereby the faucetcan be opened only after unlocking the padlock.

For faucets having the single or crankhandle 5 for turning the valve theblock 6 need have but one longitudinal slot 8 in its side wall, althoughon such faucets a block of the neccessary dimensions having the twoslots 8 can be employed.

It is evident that various changes and modifications might be resortedto in the forms, constructions, and arrangements of the parts describedwithout departing from the spirit and scope of my invention. Hence I donot wish to limit myself to the exact constructions shown.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A faucet-lock comprising a block open at bottom, the front and rearwalls being recessed to straddle and rest upon the body of the faucetand support the lock, the sidewall of the block being bifurcated toreceive the key of the faucet, the walls of said bifurcation engagingthe wing of the faucet-key and preventing movement thereof.

2. As an article of manufacture, a faucetlock consisting of a hollowblock open at the lower end and havinga side wall slotted longitudinallyfrom the lower end upwardly to snugly receive the faucet-key to hold thesame against movement, said faucet-key adapted to project outwardlybetween the walls of the slot and below the upper end thereof, the frontand rear walls of said block being longitudinally slotted for acomparatively short distance upwardly to snugly straddle the faucet-bodyand thereby center the block thereon and hold the same againsthorizontal oscillation, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
